Simulations for the MIMOSIS-1 CMOS Monolithic Active Pixel Sensor — •Hasan Darwish for the CBM-MVD collaboration — Goethe University Frankfurt

MIMOSIS is a CMOS Monolithic Active Pixel Sensor designed to be used for the Micro Vertex Detector (MVD) of the future CBM experiment at FAIR in Darmstadt. The 50 um thick sensor featuring 1024 x 504 pixels with a pitch of 27 x 30 um will have to combine a spatial resolution of ~ 5 um with a time resolution of 5 us and provide a peak rate capability of 80 MHz/cm^2. Simulations have been done for the first prototype, MIMOSIS-1, using Allpix-squared simulation software. The simulations aim to reproduce the findings obtained in the sensor beam tests at DESY, COSY and CERN. The simulations as well as the reference data will be presented. *This work has been supported by BMBF (05P21RFFC2), HFHF, GSI, HGS-HIRe and Tangerine.
